* x86: refactor ->enable_apic_mode() subarch methodsIngo Molnar2009-01-28
| | | | | | | | | | | Only ES7000 has a real ->enable_apic_mode() method, the other subarchitectures define it but keep it empty. So mark the vector as NULL, extend the generic code to handle NULL -setup_portio_remap() entries and remove all the empty handlers. Signed-off-by: Ingo Molnar <mingo@elte.hu>
* x86: refactor ->check_phys_apicid_present() subarch methodsIngo Molnar2009-01-28
| | | | | | | | | - spread out the namespace to per driver methods - extend it to 64-bit as well so that we can use apic->check_phys_apicid_present() unconditionally Signed-off-by: Ingo Molnar <mingo@elte.hu>
* x86: refactor ->setup_portio_remap() subarch methodsIngo Molnar2009-01-28
| | | | | | | | | | | | | | Only NUMAQ has a real ->setup_portio_remap() method, the other subarchitectures define it but keep it empty. So mark the vector as NULL, extend the generic code to handle NULL -setup_portio_remap() entries and remove all the empty handlers. Also move the NUMAQ method from the header file into the apic driver .c file. Signed-off-by: Ingo Molnar <mingo@elte.hu>

* x86, apic: streamline the ->multi_timer_check() quirkIngo Molnar2009-01-28
| | | | | | | | | | | | only NUMAQ uses this quirk: to prevent the timer IRQ from being added on secondary nodes. All other genapic templates can have a NULL ->multi_timer_check() callback. Also, extend the generic code to treat a NULL pointer accordingly. Signed-off-by: Ingo Molnar <mingo@elte.hu>
* x86, apic: clean up ->setup_apic_routing()Ingo Molnar2009-01-28
| | | | | | | | | | - separate the namespace - remove macros - remove namespace clash on 64-bit Signed-off-by: Ingo Molnar <mingo@elte.hu>

* x86, apic: clean up ->vector_allocation_domain()Ingo Molnar2009-01-28
| | | | | | | | | | | | - separate the namespace - remove macros - move the default vector-allocation-domain to mach-generic - fix whitespace damage Signed-off-by: Ingo Molnar <mingo@elte.hu>
* x86, apic: remove no_balance_irq and no_ioapic_check flagsIngo Molnar2009-01-28
| | | | | | | These flags are completely unused. (the in-kernel IRQ balancer has been removed from the upstream kernel.) Signed-off-by: Ingo Molnar <mingo@elte.hu>
* x86, apic: clean up check_apicid*() callbacksIngo Molnar2009-01-28
| | | | | | | Clean up these methods - to make it clearer which function is used in which case. Signed-off-by: Ingo Molnar <mingo@elte.hu>
* x86, apic: rename genapic::apic_destination_logical to genapic::dest_logicalIngo Molnar2009-01-28
| | | | | | This field name was unreasonably long - shorten it. Signed-off-by: Ingo Molnar <mingo@elte.hu>
* x86: clean up the APIC_DEST_LOGICAL logicIngo Molnar2009-01-28
| | | | | | | | | | | | | | | Impact: cleanup The bigsmp and es7000 subarchitectures un-defined APIC_DEST_LOGICAL in a rather nasty way by re-defining it to zero. That is infinitely fragile and makes it very hard to see what to code really does in a given context. The very same constant has different meanings and values - depending on which subarch is enabled. Untangle this mess by never undefining the constant, but instead propagating the right values into the genapic driver templates. Signed-off-by: Ingo Molnar <mingo@elte.hu>
* x86: rename ->ESR_DISABLE to ->disable_esrIngo Molnar2009-01-28
| | | | | | | | the ->ESR_DISABLE shouting variant was used to enable the esr_disable macro wrappers. Those ugly macros are removed now so we can rename ->ESR_DISABLE to ->disable_esr Signed-off-by: Ingo Molnar <mingo@elte.hu>
* x86: clean up esr_disable() methodsIngo Molnar2009-01-28
| | | | | | | | | | | | | | Impact: cleanup Most subarchitectures want to disable the APIC ESR (Error Status Register), because they generally have hardware hacks that wrap standard CPUs into a bigger system and hence the APIC bus is quite non-standard and weirdnesses (lockups) have been seen with ESR reporting. Remove the esr_disable macros and put the desired flag into each subarchitecture's genapic template directly. Signed-off-by: Ingo Molnar <mingo@elte.hu>
* x86, apic: clean up / remove TARGET_CPUSIngo Molnar2009-01-28
| | | | | | | | Impact: cleanup use apic->target_cpus() directly instead of the TARGET_CPUS wrapper. Signed-off-by: Ingo Molnar <mingo@elte.hu>
* x86, apic: clean up target_cpus methodsIngo Molnar2009-01-28
| | | | | | | | | | Impact: cleanup Clean up all the target_cpus() namespace overlap that exists between bigsmp, es7000, mach-default, numaq and summit - by separating the different functions into different names. Signed-off-by: Ingo Molnar <mingo@elte.hu>
* x86, apic: remove IRQ_DEST_MODEIngo Molnar2009-01-28
| | | | | | Remove leftover definition. Signed-off-by: Ingo Molnar <mingo@elte.hu>
* x86, apic: remove ES7000_IRQ_DELIVERY_MODE and ES7000_IRQ_DEST_MODEIngo Molnar2009-01-28
| | | | | | | | | Impact: cleanup They were only used in a single place and obscured the apic_es7000 driver template. Signed-off-by: Ingo Molnar <mingo@elte.hu>
* x86, apic: remove BIGSMP_IRQ_DELIVERY_MODE and BIGSMP_IRQ_DEST_MODEIngo Molnar2009-01-28
| | | | | | | | | Impact: cleanup They were only used in a single place and obscured the apic_bigsmp driver template. Signed-off-by: Ingo Molnar <mingo@elte.hu>
* x86, apic: remove NUMAQ_IRQ_DELIVERY_MODE and NUMAQ_IRQ_DEST_MODEIngo Molnar2009-01-28
| | | | | | | | Impact: cleanup They were only used in a single place and obscured the apic_numaq template. Signed-off-by: Ingo Molnar <mingo@elte.hu>
* x86, apic: remove SUMMIT_IRQ_DELIVERY_MODE and SUMMIT_IRQ_DEST_MODEIngo Molnar2009-01-28
| | | | | | | | Impact: cleanup They were only used in a single place and obscured the apic_summit template. Signed-off-by: Ingo Molnar <mingo@elte.hu>
* x86, apic: remove DEFAULT_IRQ_DELIVERY_MODE and DEFAULT_IRQ_DEST_MODEIngo Molnar2009-01-28
| | | | | | | | Impact: cleanup They were only used in a single place and obscured the apic_default template. Signed-off-by: Ingo Molnar <mingo@elte.hu>
* x86, apic: remove IRQ_DEST_MODE / IRQ_DELIVERY_MODEIngo Molnar2009-01-28
| | | | | | | | | | | | | Remove the wrapper macros IRQ_DEST_MODE and IRQ_DELIVERY_MODE. The typical 32-bit and the 64-bit build all dereference via the genapic, so it's pointless to hide that indirection via these ugly macros. Furthermore, it also obscures subarchitecture details. So replace it with apic->irq_dest_mode / etc. accesses. Signed-off-by: Ingo Molnar <mingo@elte.hu>
* x86, genapic: rename int_delivery_mode, et. al.Ingo Molnar2009-01-28
| | | | | | | | | | | | | | | int_delivery_mode is supposed to mean 'interrupt delivery mode', but it's quite a misnomer as 'int' we usually think of as an integer type ... The standard naming for such attributes is 'irq' - so rename the following fields and macros: int_delivery_mode => irq_delivery_mode INT_DELIVERY_MODE => IRQ_DELIVERY_MODE int_dest_mode => irq_dest_mode INT_DEST_MODE => IRQ_DEST_MODE Signed-off-by: Ingo Molnar <mingo@elte.hu>
* x86: clean up apic->apic_id_registered() methodsIngo Molnar2009-01-28
| | | | | | | | | | | | | | | Impact: cleanup x86 subarchitectures each defined a "apic_id_registered()" method, which could be an inline function depending on which subarch we build for, and which was also the name of a genapic field. Untangle this namespace spaghetti by giving each of the instances a separate name. Also remove wrapper macro obfuscation. Signed-off-by: Ingo Molnar <mingo@elte.hu>
* x86: clean up apic->acpi_madt_oem_check methodsIngo Molnar2009-01-28
| | | | | | | | | | | | | | | | | Impact: refactor code x86 subarchitectures each defined a "acpi_madt_oem_check()" method, which could be an inline function, or an extern, or a static function, and which was also the name of a genapic field. Untangle this namespace spaghetti by setting ->acpi_madt_oem_check() to NULL on those subarchitectures that have no detection quirks, and rename the other ones (summit, es7000) that do. Also change default_acpi_madt_oem_check() to handle NULL entries, and clean its control flow up as well. Signed-off-by: Ingo Molnar <mingo@elte.hu>
* x86: remove APIC_INIT / APICFUNC / IPIFUNCIngo Molnar2009-01-28
| | | | | | | | | The APIC_INIT() / APICFUNC / IPIFUNC macros were ugly and obfuscated the true identity of various APIC driver methods. Now that they are not used anymore, remove them. Signed-off-by: Ingo Molnar <mingo@elte.hu>
* x86, genapic: cleanup 32-bit apic_summit templateIngo Molnar2009-01-28
| | | | | | | | | | Clean up the APIC driver template: - order fields properly - use the macro names explicitly (so that they can be renamed later) - fill in NULL entries as well Signed-off-by: Ingo Molnar <mingo@elte.hu>

* x86: rename 'genapic' to 'apic'Ingo Molnar2009-01-28
| | | | | | | | Rename genapic-> to apic-> references because in a future chagne we'll open-code all the indirect calls (instead of obscuring them via macros), so we want this reference to be as short as possible. Signed-off-by: Ingo Molnar <mingo@elte.hu>
* x86, genapic: provide IPI callbacks unconditionallyIngo Molnar2009-01-28
| | | | | | | 64-bit x86 uses the IPI callbacks even on UP - so provide them generally. Signed-off-by: Ingo Molnar <mingo@elte.hu>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Impact: re-enable CPUID unmasking on affected processors As far as I am capable of discerning from the documentation, MSR_IA32_MISC_ENABLE should be available for all family 0xf CPUs, as well as family 6 for model >= 0xd (newer Pentium M). The documentation on this isn't ideal, so we need to be on the lookout for errors, still. Signed-off-by: H. Peter Anvin <hpa@zytor.com>
